Embodiment Construction

[0020] figure 1 The shown spring washer 1 is arranged in a motor vehicle and supports a helical spring 2 on one side, on the other side the spring washer 1 rests on a spring retainer (not shown) and thus rests on the helical spring (hereinafter also referred to as between the spring) 2 and the spring retainer.

[0021] The spring pad 1 comprises a base body 10 made of an elastomer. The basic body 10 serves to support the spring 2 and to dampen the sound of the spring relative to the vehicle body. For this purpose, the base body 10 is made of a soft, shock-absorbing material, such as rubber. The spring pad 1 also includes a sacrificial anode 20 . This sacrificial anode 20 is arranged on the spring side, so that said sacrificial anode is in direct contact with the spring 2 . Since the sacrificial anode 20 is made of a non-noble metal, such as zinc, it has a corrosion-proof effect on the spring 2 . An insert 30 made of a strong material is also embedded between the sacrifici...

Abstract

The invention relates to a spring pad arranged between a sprial spring and a spring retainer for a motor vehivle. The spring pad comprises a base body made of elastomer and a scarifice anode arranged on the base body besides the spring. The spring pad is charaterized in that, an embedded piece made of firm materials is embedded between the scarifice anode and the base body, and embedded piece is used for supporting the scarifice anode.

Description

technical field [0001] The invention relates to a spring washer for a motor vehicle which is arranged between a helical spring and a spring retainer, said spring washer comprising a base body made of an elastomer and a sacrificial anode. Background technique [0002] Such spring pads are used, for example, in spring arrangements for wheel suspensions. The spring pad serves here to support and dampen the coil spring. In addition, the spring pad also acts as a protection against corrosion of the spring. Especially in the region of the wheel suspension, the springs are subjected to high loads and are subjected to extreme weather conditions, whereby the springs must not only be well supported, but must also be protected against corrosion over a long period of time. [0003] Such a spring washer is known, for example, from DE 100 09 136 A1. The base body described here consists of an elastomer and is provided with an intermediate plate. This intermediate plate also acts as a ...
